  • To assess the clinical benefits of contrast-enhanced ultrasound in various vascular applications.

Main Methods:

  • Review of available and developing ultrasound contrast agents.
  • Discussion of the interaction between contrast agents and ultrasound, including harmonic imaging.
  • Analysis of clinical data and author experience for diverse vascular applications.

Main Results:

  • Exploration of various types of ultrasound contrast agents and their characteristics.
  • Consideration of the advantages of harmonic imaging when using contrast agents.
  • Review of potential clinical benefits in cerebral, peripheral, and abdominal vasculature.

Conclusions:

  • Ultrasound contrast agents have the potential to significantly improve peripheral vascular imaging.
  • Further research and clinical adoption are needed to realize the full benefits of these agents.
  • Contrast-enhanced ultrasound shows promise across a range of vascular imaging scenarios.
